INSA- Senior Scientist,Documented unmistakable evidences for 2700 Ma glacial deposits in the Archean Dharwar sequence. This glaciation event is the second oldest glaciation event recorded so far in the Earth History. The 2700 Ma glaciation event could have global significance, because such rocks have been found in Botswana of south Africa and Stillwater area of Montana , USA. India was near the pole Ca 2700 Ma.

2018 till present:
Visiting Professor,Divecha Centre for Climate Change, IISc,While continuing my work which is mentioned under my activity as Research associate, I have worked on Archaean atmospheric density as verified from fossil rain drop imprints. Have initiated a programme on Geogenic Polutants of groundwater in south Asian Countries. First brain storming session will be held in the DCC on this aspect in June 20-21, 2018.

Research activities

Working on finding out reasons for Archean glaciation in India

Working on stable isotope and REE geochemistry of auriferous quartz carbonate veins. Have worked on this aspect on two deposits ( Ajjanhalli and G.R. Halli) in Karnataka so far which show that gold bearing hydrothermal solutions were derived from the mantle. Investigations on other gold prospects in Karnataka and Andhra Pradesh are in progress.

Have acquired new SHRIMP Zircon U-Pb ages on the felsic volcanics of the Dharwar Supergroup. The data suggest support the views of myself and late Prof. Naha that the Eastern and western Dharwar craton have correlatable rocks and evolved as a single terrane. They are not two terranes sutured as postulated by some other workers.

Have begun detailed isotopic investigation on iron, manganese and limestone deposits of the Dharwar craton in collaboration with Pondicherry university to examine evidences of Archean life/biological activity and its role in giving rise to large iron and manganese deposits in the Archean. It was generally believed that Archaean iron formations are hydrothermal. Studies in progress show that there are both hydrothermal and hydrogenous. Their precipitation is mediate by bacterial photosynthesis.

RESEARCHES ON OTHER ROCK FORMATIONS
Researches on Aravalli Group

A comparative study of geochemistry of Archaean and Proterozoic rocks was undertaken while supervising the Ph.D work of Dr. B. Sreenivas. In this study it was shown that there is no significant change in the abundance of transitional group elements across the Archean- Proterozoic boundary. There is an alumina enriched paleosol at the base of Arvalli Supergroup, which indicates weathering under reducing conditions prior to the deposition of Aravalli Supergroup. The study of carbonates from Ghasiar area brought out the first evidence heavy δ 13C excursion in the carbonates immediately overlying the Jhamarkotra stromatolitic dolomite horizon.

Researches on Cuddapah

Pb-Pb isotopic dating of Vempalli domites was reported at 1756±29Ma ( With Zacharia, Gopalan and Bhaskar Rao)

Research on Kaladgi

Supervising post- doctoral research work of Dr. Sambasiva Rao, detailed geochemical study of shales from different stratigraphic horizons of the Kaladgi Supergroup was undertaken. It was found that the lower Kaladgi shales are richer in transition group elements and depleted in Zr, while the upper shales are enriched in Zr and depleted in Fe, Mg, Mn, Cr and Ni. The stripping of the Dharwar supracrustal cover and exposure of the basement granitoids could be demonstrated through this study.

Researches on Deccan Trap

Srinivasan discovered new phreatomagmatic eruptive centres southeast of Jabalpur. In a detailed study of the minerals present in the amygdales of Deccan traps, with Dr. Parthasarathy, he found saponite clay which was capable of removing hexavalent chromium from polluted waters. He also found a new phase of Si – moganite in the amygdales.

IMPORTANT CONTRIBUTIONS FOR THE ARCHEAN REGION OF KARNATAKA AS A GEOLOGICAL CONSULTANT

Srinivasan was a geological consultant also. Some important investigations carried out during that period are given below.

Srinivasan along with Dr. B.L. Sreenivas interpreted the satellite imagery of the Dharwar craton and produced the first lineament map of Karnataka. This map was used to explore for ground water in difficult hard rock areas of Karnataka under the Ganga Kalyana scheme of the Government of Karnataka and many successful bore wells were got drilled on productive lineaments. Significant among them are the wells near Chiknaikanhalli and Gauribidanur which supported water supply for a while.

Combining the tracing of lineaments from LANDSAT imagery, geological mapping on large scale and geophysical studies (electrical resistivity), he identified weak zones along tunnel alignments of irrigation tunnels ( Bagur-Navile, Arkalgud, Kadabgatti etc) which saved heavy costs on drilling and provided useful guidelines for tunneling.

Srinivasan proved several million cubic metres of puddle clay and filter material through soil mechanics studies in collaboration with Build Met Pvt.Ltd for the construction of the Lakya Dam (tailing dam) of the Kudremukh iron ore project.

From a detailed study of Atterberg limits and green strength of the clays, Srinivasan showed the feasibility of use of clays from the upper layers in Bageshpur area of Hassan for making stoneware pipes. A factory based on this was set up by Mysore Minerals Ltd., which ran for more than a decade.

Srinivasan demarcated abrasive grade bauxites amidst metallurgical grade bauxites from Baindur plateau, Karnataka in a study for Carborundum Universal Ltd.

He along with Dr. B.L. Sreenivas and Mr. R.H. Sowkar (then with the Mysore Minerals Ltd., ) estimated the manganese resources that would get submerged by the Supa Reservoir of the Kali Nadi hydroelectric Project of Karnataka. The report formed the basis for marketing of manganese ore by Mysore Minerals Ltd. to M/S Marubeni Corporation, Japan.

As a consultant to Geomysore India Pvt.Ltd, he wrote more than 100 exploration reports along with Dr. V.N. Vasudev on gold exploration in Karnataka and Andhra, Pb-Zn in Maharashtra, Gold and nickel in Madhya Pradesh. These preliminary exploration reports have led to maturation of projects for obtaining mining licenses for gold so far in Ganajur in Karnataka and Jonnagiri in Andhra Pradesh.
